A method for rapid separation of serum or plasma from cells in a whole blood sample uses a cylindrical sample tube having longitudinally-extending internal ribs. A separation gel and the sample are introduced into the tube, and the tube is axially centrifuged so as to form concentric shells of cells, gel, and serum or plasma. After centrifugation is stopped, the serum or plasma collects in the tube by gravity flow and the cells and gel remain affixed to the walls and ribs of the tube.
